The European gypsy moth (Lymantria dispar L.) was first introduced to Massachusetts in 1869 and within 150 years has spread throughout eastern North America. This large-scale invasion across a heterogeneous landscape allows examination of the genetic signatures of adaptation potentially associated with rapid geographic spread. We tested the hypothesis that spatially divergent natural selection has driven observed changes in three developmental traits that were measured in a common garden for 165 adult moths sampled from...
Data from: Modeling multilocus selection in an individual-based, spatially-explicit landscape genetics frameworkErin Landguth, Brenna R. Forester, Andrew J. Eckert, Andrew J. Shirk, Mitra Menon, Amy Whipple, Casey C. Day & Samuel A. Cushman
We implemented multilocus selection in a spatially-explicit, individual-based framework that enables multivariate environmental gradients to drive selection in many loci as a new module for the landscape genetics programs, CDPOP and CDMetaPOP. Our module simulates multilocus selection using a linear additive model, providing a flexible platform to evaluate a wide range of genotype-environment associations. Importantly, the module allows simulation of selection in any number of loci under the influence of any number of environmental variables....
Data from: Tracing the footprints of a moving hybrid zone under a demographic history of speciation with gene flowMitra Menon, Erin Landguth, Alejandro Leal-Saenz, Justin Bagley, Anna Schoettle, Christian Wehenkel, Lluvia Flores-Renteria, Sam Cushman, Kristen Waring & Andrew Eckert
A lack of optimal gene combinations, as well as low levels of genetic diversity are often associated with the formation of species range margins. Conservation efforts rely on predictive modelling using abiotic variables and assessments of genetic diversity to determine target species and populations for controlled breeding, germplasm conservation and assisted migration. Biotic factors such as interspecific competition and hybridization, however, are largely ignored, despite their prevalence across diverse taxa and their role as key...

ABSTRACT Purpose: While there is strong evidence supporting the importance of telemedicine in stroke, its role in other areas of neurology is not as clear. The goal of this review is to provide an overview of evidence-based data regarding the role of teleneurology in the care of patients with neurologic disorders other than stroke. Recent findings: Studies across multiple specialties report noninferiority of evaluations by telemedicine compared with traditional, in-person evaluations in terms of patient...
Using stable isotopes to estimate migratory connectivity for a patchily distributed, wetland-associated Neotropical migrantJessie Reese
Estimates of migratory connectivity are needed for full annual cycle population models of migratory bird species experiencing rapid declines in abundance. One technique to determine migratory connectivity is through stable isotope analysis. This low-resolution method may be influenced by how data are calibrated between isotopes measured in precipitation and those measured in feathers, and can be informed by incorporating relative abundance into the assignment model. eBird abundance maps are a new tool combining citizen science...
Understanding migratory connectivity is essential for determining the drivers behind population dynamics and for implementing effective conservation strategies for migratory species. Genetic markers provide a means to describe migratory connectivity, however they can be uninformative for species with weak population genetic structure, which has limited their application. Here, we demonstrated a genomic approach to describing migratory connectivity in the prothonotary warbler, Protonotaria citrea, a Neotropical songbird of conservation concern. Using 26,189 SNPs, we revealed regional...
Data from: Using digitized museum collections to understand the effects of habitat on wing coloration in the Puerto Rican monarchMariangeli Echevarria Ramos & Catherine M. Hulshof
Given the recent emphasis on Lepidoptera wing color and temperature in macroecology, we briefly describe known drivers of wing color and outline the use of images for understanding color variation across space and time. As a case study, we quantify wing color using museum specimens of the non-migratory Puerto Rican monarch. In contrast to recent findings, we report darker individuals in coastal habitats, underscoring the need to include other selection factors. We detail how international...
Objective: To determine the frequency and relative importance of the most meaningful symptoms in facioscapulohumeral muscular dystrophy (FSHD) and to identify the demographic and clinical features that are associated with the greatest disease burden in this population. Methods: We performed a cross-sectional study involving 328 FSHD participants. Collectively, participants reported the prevalence and relative importance of 274 symptoms and 15 symptomatic themes. We assessed the association between symptomatic theme prevalence and participants’ age, sex, disease...
